MAGAZINE- GUN.

To all whom it may concern:

Be it'kno'wn that I, FRANCESCO DUmnno, a subject of the King of Italy,residing in the borough of Manhattan, in the county of New York andState of New York, have invented certain new and useful Improvements inMagazine-Guns, of which the following is a specification, referencebeing had therein to the accompanying drawings, forming part thereof.

My invention relates to magazine guns and more particularly relates tomilitary rifles.

An object of'my invention is to produce a gun of the magazine type ofpractical c011- struction and of large magazine capacity and of largercapacity than the practical guns of this type commonly in use.

Other more particular objects are positiveness and certainty of action,convenience of operation including quickness and facility in rechargingthe magazine, and other objects and advantages which will hereinafterappear.

In carrying out my invention, the cartridges are stored in asubstantially erect position in a magazine in the stock of the gun andare fed forward, successively tilted, and conveyed forwardbullet-foremost through a throat in the hand-hold of the stock to theloading mechanism at the breech of the gun. The cartridges are supportedin the magazine in removable holders, and

a reserve supply of cartridges may be carried in extra or additionalsimilar cartridge holders.

My invention includes improvements in the magazine, including improvedremovable cartridge-containing holders forming part of the magazine,improved feeding means for feeding the cartridges from'the magazine,improved conveying mechanism for bringing the cartridges forward to theloading mechanism, and also includes transfer mechanism for transferringthe cartridges from the magazine to the conveying mechanism.

More in detail, my invention includes a reciprocative conveyer actuatedby a rack and pinion.

My invention also includes in combination a cartridge transferreceptacle mounted for tilting movement.

My invention also includes a retractile Specification of Letters Patent.

spring (more particularly an extensible coiled spring) passing around a.sheaveand attached to a follower for feeding the cartridges through andfrom the magazine.

My invention also includes other features of construction andcombinations of parts as will appear from the following descrip tion.

I shall now describe the magazine rifle illustrated in the accompanyingdrawings and embodying my invention and shall thereafter point out myinvention in claims.

Figure 1 is a side elevation of the rifle with the bolt in retracted.position and having the outer portion of the barrel broken away andparts of the stock and one of the breech-plates removed. Fig. 2 is aplan view of what is shown in Fig. l but with both rearward side partsof the stock in position. Fig. 3 is a view similar to Fig. l but withthe bolt at firing position, the barrel and the spring case in section,the left side of the stock in place, and having the cartridge holders ofthe magazine and other parts omitted. Fig. 3" is a section on a planeindicated by the line 3"3 of Fig. 3 as viewed from the left. Fig. 4 is aview similar to Fig. 1 from the other side of the gun and having partsof one of the car tridge holders broken away. Fig. 5 is a plan view ofthe lower part of the stock frame and the mechanisms carried thereby, apart of the stock being in longitudinal section. Fig. 6 is an enlargedface view of one of the cartridge holders which form removable parts ofthe magazine. Fig. 7 is an end view of the holder shown in Fig. 6 asseen from the left. Fig. 8 is a further enlarged partial centralvertical section on a plane indicated by the line 88 of Fig. 6 as viewedfrom the left. Fig. 9 is a perspective view of parts of the magazine andits adjuncts, drawn to the scale of Figs. 6 and 7. Fig. 10 is a partialplan illustrating the feeding of the cartridges from the magazine to thetransfer receptacle, the scale be ing that of Figs. 6, 7 and 9. Fig. 11is a further enlarged perspective view of the cartridge transferreceptacle and a portion of the magazine guard carried thereby. Fig. 12is a perspective view of the cartridge conveyer, drawn substantially tothe scale of Fig. 11. Fig. 13 is a perspective view of the cartridgefeeding follower and the catch for holding it at retracted positiontogether with adjacent portions of the butt of the gun, the scale beingslightly greater than in Fig. 11. Fig. 1 1- is a side view from the leftside of the breech frame and its adjuncts, the scale of drawing beingsubstantially that of Figs. 6 and 7. Fig. 15 is a plan view of the boltto the same scale as Fig. 14.

In the magazine rifle illustrated in the drawings, the magazine in thestock will contain twenty cartridges, which with one in the barrel andanother on the way from the magazine to the barrel, gives twentytwoshots as the maximum capacity of the gun. The cartridges are supportedin holders or containers 1, constituting removable parts of themagazine. Two of the holders 1 may be placed at the same time in thegun, there being ten cartridges in each holder, and any additionalconvenient number of charged holders may be carried on the person. Theholders 1 may be of. sheet metal and are provided with top and bottomcartridgeretaining flanges, as shown in the drawings. In charging theholders the cartridges are slipped into the ends of the holders and areretained by the top and bottom flanges. After the cartridges have beenplaced in the holder and until such time as the holder may be insertedin the gun as a part of the magazine, the cartridges, whether a fullcharge or a less number, are prevented from slipping out at the ends ofthe holder and are properly spaced in the holder by pivoted prongs 2carried by a common rock shaft 3 at the back of the holder andprojecting at the respective ends of and through slots in the back ofthe holder, and properly spaced so that with a full charge of cartridgesthey will project between the cartridges and at each side of eachcartridge. The rock shaft has bearings in small clips 1 secured to theback of the holder. The rock shaft and prongs are actuatable to projector retract the prongs 2 by a small handle 5 which has some lost motionon the rock shaft 3 so that it .will lie flat against the back of theholder in either position of the prongs. The rotary movement of thehandle 5 on the shaft 3 is limited by the projecting part of the middleprong 2 in one direction and in the other direction by a stop shoulderat the back of the same prong (Fig. 8).

In Figs. 6, 7 and 8 the cartridge-holding prongs 2 are shown in theirprojected cartridge-holding position. When these prongs are retractedthey will fold back into the slots through which they project, so as toleave the inner surface of the holder unobstructed. In Fig. 8 the handle5 is shown in broken lines as moved downward to the extent of taking upits lost motion, if moved farther down it would retract the prongs.

After the holders are placed in the gun the prongs 2 are retracted topermit the feeding of the cartridges along and from the holders as thegun is successively fired and reloaded. The rock shaft 3 has suflicientfriction in its bearings to remain in either of its positions; and whenthe prongs 2 have been retracted with the holders in the gun they mustremain in this position because of the fact that the handles 5 will beprevented from swinging out by a hinged door 6 provided in the left sideof the stock (Fig. 3) for the insertion and removal of the holders 1,this door being held closed by a suitable catch 7. When the holders 1are inserted in the gun, as parts of the magazine, they are slippedupward under rigid hooks 8 and against bent leaf springs 9 and rest upona guideway 10 at the bottom and fit with their faces close up to thelongitudinally slotted wall of a flattened tubular spring case 11, tothe other or unslotted side of which the hooks 8 and leaf springs 9 aresecured. Two holders are arranged in tandem, one behind the other, andlongitudinal slipping of the holders is prevented by shoulders 12forming between them a notch which re ceives one of the springs 9. Itwill be noted that the springs 9, by reason of their pressure upon theholders 1 above the points of contact therewith of the downwardlyextending end portions of the hooks 8, will actto retain the holders inplace.

The cartridges are under constant spring pressure tending to feed themforward through and out of the holders as fast as they are used. Themechanism for thus feeding the cartridges forward includes a long coiledfeed spring 13 contained in the spring case 11. The upper end of thisspring, as perhaps best seen in Fig. a, is hooked over the rear end ofthe spring case, whence the spring extends forward and passes around asmall sheave or pulley 14tpivoted in the spring case, and then eX- tendsrearward toward the butt of the gun. The rearwardly extending end of thespring 13 is attached to a plug 15 loosely slidable in a slotted guidetube 16 fixed in the spring case 11 with the slot therein registeringwith the slot of the spring case. The slidable plug 15 has a lug 17projecting through the slot in the side of the spring case 11 andrigidly secured to the rear plate 18 of a follower. The follower has afront plate 19 which is at the rear of and pushes against therearmostcartridge. The front plate 19 and the rear plate 18 areconnected by coiled thrust springs 20 and these springs are guided bytelescopic studs 21 and 22 carried by the front and rear platesrespectively, and cooperative with intermediary telescopic members 23(Fig. 13). The front plate 19 is provided with a rearwardly extendingsteaclying tongue 24. The follower A springs are supplemental to themain feed spring 13 and cooperate therewith in forcing out the lastcartridges.

A spring-messed catch is pivoted inside the stock at the butt of the gunand is adapted to engage a notch shown in the exposed edge of the lug 17for holding the follower at the retracted position while the cartridgeholders 1 are being inserted or removed, and 'the catch 25 is pressed tothe engaging position by a small bent leaf spring 26. V

A plate 27 has a substantially vertical inclined cam face closing theforward end of the magazine, which has a lateral mouth or cartridge exitopening just forwardly of the spring case, the forward end of the latterbeing closed (Fig. 10). When the foremost cartridge is pushed from theforward holder 1, by the pressure of the follower upon the rearmostcartridge, it is pushed against the vertical inclined face of the camplate 27. The transfer mechanism for receiving the cartridges from themagazine and delivering them to the conveying mechanism, will now bedescribed.

The vertical cam face of the plate 27 forces the cartridge to the rightout of alinement with the holders 1 and to a position in front of thesheave 14 and in alinement with the spring case 11. At this point thecartridge is receivedinto a pivoted and sliding carriage or transferreceptacle 28, which is brought into the rearward and vertical position1 and 4:) by the backward movement of the bolt 29 in the loadingoperation, but normally this carriage occupies a reclining and forwardposition (Figs. 3 and There is a plate 30 at the right of the carriage28 and this plate, which is shown as an extension of the right wall ofthe spring case 11, acts as a lateral stop'for the cartridge andprevents it from being pushed through the carriage, which is of U-shape,the forward or lower leg of the U being split, the split or bifurcationextending into the bottom of the carriage (see Fig. 11). Thecarriage 28is mounted for tilting and reciprocative increments and is provided withcombined pivot pins and guide pins 31. The carriage 28 is guided betweena forward extension of the cam plate 27 on the left and a guide plate onthe right and extending forward from the stop plate 30. The forward andrearward movements of the carriage 28 are limited by a slot in the guideplate 32, as seen in Figs. 1 and 3, the slot being curved downward atthe rear end to facilitate the tilting of the carriage 28. When thecarriage 28 is at its normal or forward position, the vertical openingor month through which the cartridges are fed when pressed against thecam plate 27 is closed to the passage of cartridges by the edge of aleaf spring 33 extending into the lower part of the spring case 11 andhinged at its forward end to the rear side of the carriage 28 (Figs. 3,5 and 11) so as to be pulled forward by the carriage 28 to form a guardacross the cartridge exit.

The carriage 28 is actuated in its sliding movement by a pivoted link34:, (Figs. 4: and 5) by which it is connected to a sliding bar 35sliding through guide loops on the forward part of the gun stock frame,as shown in the drawings. The rearward end of the lililIBt is pivotallyconnected to the transfer carriage 28 by a screw stud 36 which rigidlyprojects from a lug on the carriage 28 to the left beyond the forwardextension of the cam plate 27 (Figs. i and 5), the plate 27 at thispoint being cut on an arc and also forwardly slotted (Fig. l) to guidethe stud 36 and thus assist in guiding the carriage 28 in its tiltingand sliding movements. The bar has an up-. ward projection 37, the endof which is received in a notch 38 (Fig. 15) in the bolt 29 so that thebar 35 is directly reciprocated by the bolt 29. When the bolt 29 ispulled back, the carriage 28 is brought to the rear and upright orcartridge-receiving pcsition (F 1 and 4t) and when the bolt is movedforward the carriage 28 contain ing the cartridge is tilted to a nearlyhori zontal position and carried forward (Figs. 3 and During the nextcomplete movement backward and forward of the bolt 29, the cartridge inthe carriage 28 will have been replaced by anotherand the formercartridge will have been carried farther forward by the conveyingmechanism and inserted into the barrel by the loading mechanismincluding the bolt 29.

The conveying mechanism will now be described.

The mechanism for taking the cartridge from the carriage 28 and bringingitforward to the loading mechanism is actuated from the bar 35, which isa rack bar having teeth meshing with those of a spur pinion 39 pivotedon a vertical stud 40 carried by the frame of the stock under the breechof the gun barrel and on which is also pivoted a spur gear ll which ismounted to rotate with the pinion 39. The gear 41 meshes with the teethof a rack bar 42 located at the right side of the gun and slidingthrough guide loops as shown, the other rack bar 35 being at the left(Fig. 5), the movements of the two rack bars being in oppositedirections and the rack bar 42 moving fart-her and faster than the rackbar to the extent of the difference in diameter of the gear and thepinion.

The rack bar 42 is connected by a pivoted link 43 to a sliding conveyerblock eta traveling in a guideway 45 which partly surrounds the conveyerblock, leaving exposed only the upper part of the right side and theadjacent portion of the top. The conveyer block 44 is of U-shapetransversely, providing a slot or deep groove in its top in which ispivoted a finger or catch 46 which normally projects upwardly andforwardly at an inclination and is yieldingly pressed to this positionby a small bent leaf spring 47 and has a shoulder coming in contact withthe bottom of the groove in the conveyer block to limit its outwardmovement (Fig. 12). The path of the conveyer block 44 overlaps that ofthe transfer carriage 28, the conveyer passing under the carriage (Fig.3), and the spring-pressed finger or catch 46 is adapted to engage thebase of the cartridge in the carriage 28 through the slot in thecarriage. As the bolt 29 is again moved backward the transfer carriage28 is retracted and the conveyer block 44 travels forward, the finger 46pulling with it the cartridge from the carriage, the cartridge at firstsliding along the top of the guideway 45 and then riding upward on aninclined bowed leaf spring 48 resting at its rear end upon the top ofthe guideway 45 and at its forward end merging into a cartridge lifteror cartridge shifter 49 having a supporting lever arm 50 extendingforward and hinged to the extreme forward end of the gun stock frame.The shiftersupporting arm 50 carries a short leaf spring 51 whose freeend engages the pinion stud 40 to assist in pressing the cartridgeshifter upward. As the cartridge moves forward it-is guided by lateralwalls 52 and 53 at the right and left, respectively, which, togetherwith the upper strap of the stock frame, the top of the guideway 45 andthe bowed spring 48, form a cartridge guiding throat through which thecartridges are conveyed bullet-foremost. As the conveyer block 44travels forward the advancing cartridge will bend the springs 48 and 51until the cartridge arrives upon the lifter 49 just forwardly of theretracted bolt 29 and opposite a vertically slotted breech opening (Fig.2) in a breech frame 54 in which the bolt 29 slides. At this point thelifter springs 48 and 51 elevate the lifter 49 and raise the cartridgeinto the open breech in front of the retracted bolt 29. The cartridge isprevented from passing upward entirely through the breech frame'by therounded ends of spring-pressed studs 55 which project slightly into thebreech opening (Fig. 2). When the bolt 29 is again pushed forward thecarriage 28 will bring forward another cartridge, and the conveyer.block 44 is brought back with its finger 46 at the base of this othercartridge. This forward movement of the bolt 29 also pushes the firstcartridge into the gun barrel (Fig. 3), closes the breech of the barreland cocks the gun ready for firing, the

trigger 64 14).

breech bolt 29 being locked in closed posi tion by rotating itsprojecting handle 56 to the right to engage it with a shoulder on thebreech frame 54 (Fig. 3).

The empty shell is withdrawn from the barrel by a hook 57 at the forwardend of the bolt 29 (Fig. 15). The withdrawn shell is then ejected fromthe breech opening by the pressure of the next advancing loadedcartridge which forces the empty shell upward past the yieldable studs55.

The firing mechanism will now be described.

A firing pin 58 within the breech bolt 29 and spring-pressed to aforward position by a coiled spring 59 (Fig. 14), has an external head60 which is provided with an eccentrically located forwardly projectingtrigger bar 61 lying at the outside of the bolt 29. The bar 61 in thefinal forward movement of the bolt 29 comes into contact with theupwardly bent end of a rearwardly-extending spring arm 62, which pushesback the firing pin 58. In firing,

the spring arm 62 is drawn down by a loop or stirrup 63 forming aconnection to the The head 60 of the firing pin 58 is also provided witha guide bar 65 which is longer than the trigger bar 61 and engages inthe same slot in the top of the breech frame 54 that provides for thesliding movement of the bolt handle 56 to prevent rotation of the firingpin and consequent displacement of the trigger bar 61 when the bolt 29is fully retracted (see Fig. 4 particularly).

From what has been said hereinbefore it will be understood that eachbackward and forward movement of the breech bolt 29 extracts the emptyshell and reloads the gun, the cartridges being brought forward one byone from the magazine whose supply may be conveniently replenished fromtime to time. The details of the complete operation have beenhereinbefore described in connection with the description of theconstruction involved and illustrated in the drawings.

It is obvious that various modifications may be made in the constructionshown in the drawings and hereinbefore particularly described within theprinciple and scope of my invention.
